21GT Nitro Outrigger Kit

This is the newest version of our world record holding  21 nitro outrigger kit.
The 21 holds numerous oval and straightaway records.
Designed by
Martin Truex, Jr., Ron Zaker and Joe Petro.

All kits now ship with 4.0 degree (21G2) sponsons.

This hull is the current state of the art for riggers, and currently holds the record for the fastest ever 2 laps on a 1/4 mile course.
Designed for very low hydrodynamic drag with water shearing and anti capillary features, this hull is fast, and turns are incredible!

This is considered a full kit, as it includes carbon boom tubes, aluminum boom tube collars and 7075 aluminum turn fin.

This kit is highly pre-fabricated, and assembly is easy, thanks to the 31 page photo illustrated, step by step assembly manual.

You can use ANY 20 to 28 engine! Air cooled OR water cooled! Pull the engine out of your truggy and bolt it in!
If you have a car engine with an SG crankshaft (1/4-28 threads), you can use the
NovaRossi Buggy Engine>Marine Flywheel Adapter
